    Subject[PATCH 4.14 91/91] ALSA: usb-audio: Update documentation comment for MS2109 quirk
    Date
    From: Hector Martin <marcan@marcan.st>

    commit 74a2a7de81a2ef20732ec02087314e92692a7a1b upstream.

    As the recent fix addressed the channel swap problem more properly,
    update the comment as well.
